I have a 69 conv that has a 455 #396021 Fa in it with G heads. The block # is 33M32655. I'm thinking it a 73 block and wonder what year the G heads are from. I have been told the heads are an improvement from what would have come with it.

thanks,
Steve W.

 

G heads are 1971.

 

Yup, its a 73 block.

 

your engine block VIN stamping is one digit short ??

 

Thanks, I'll have to take another look at the block #, but 71 heads sound like a good think.
